' Specification of Letters Patent.

Patented Aug. 20, 1912.

To all whom it may concern:

Be it known that 1, WILLIAM J. Bnnonns, citi'in of" the United States,residing at Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented certain new and useful Improvements in Pop-Up Waste- Valves, ofwhich the following is a specification.

This invention relates to waste valves, and particularly to so calledpop up waste valves and fixtures used on lavatories, bath tubs and thelike.

The object of the invention is to provide an improved waste valve, andimproved operating devices for the same.

A further object ,of, the invention is to provide a fixture in which theworking parts are inc'losed', and in which all movable parts subject tofriction are submerged in oil.

A further object 'of the invention is to provide an improved connectionbetween an operating handle or button and the waste valve, in order tooperatethe latter, the valve being of the type .which is' lifted todischarge the waste water.-

Various other improvements and advantages with respect to the details.of the fixture will be evident from the following description and theaccompanying drawings.

In the drawings Figure 1 1s a vertical sectional view of the device,Fig. 2 is a sectional detail of a modification.

Referring specifically to the drawing, 10 is the waste knob or handle,provided with a metal ring 11 and connected to a rod 17 to which it isscrewed as at 14 with a lock nut 16 to hold it.

12 is a ferrule with a flange at the upper end engaging over the top ofan escutcheon 13. The ferrule screws into a tubular connection 15 whichextends through the slab of the lavatory and is fastened by a lock nut16 screwed thereon under the slab. The tube 15 is connected to a lowertube 20 by a coupling 18 with packing 19. The tube 20 is curved as shownand contains oil which fills the lower part of the tube as indicated at21.. At the lower end of the rod 17 is a piston 24, preferably formed intwo parts wlth a washer or packing 23 therebetween, to form a tightjoint with the tube, the parts being held by a lock nut 22. A chain 27is connected at 26 to the lower iston, and said chain is provided at itsjoints with rollers 28. The chain extends in the bend of the tube, andis connected to another piston 43 which projects into a special angularfitting fitting against-the bottom of the lavatory bowl. The piston 43*projects into said fitting and is pivotal'ly connected at 36 to a link44 which 'is'pivotally connected at 34 to a bell crank lever 50 pivotedat 49 on lugs 48., The side armor tube of the angular fitting 35 has aremovable bonnet 37, witha washer 38 to make a tight joint, and thelower-end of the pipe 20is connected t'oflthe bonnet by a coupling nut39 engaging flange 41 on the tube, with a washer at the joint. j I

42 is a stufiin box inside-the washer 40,

filled with packing to prevent leak of the oil in the tube, and thepiston 43 slides in said stufiing box.

4 33s a metal plate set in between the washer 38 and a shoulder 43", toform a guide for the piston 43 and to form a stop 1 against which theextended end 44 of the link strikes to prevent excessive movementbackwardly of the piston-4 "The fitting 35is connected to a coupling 47by a-nut 45 with a washer 46 at the j oint- The horizontal armnfthehellcrank 50- bears under the foot 51 of the screw 52 which is'adjustable inthe waste plug 54, to properly set the parts and take up wear orwarping. The hollow plug casing 57 is screwed into the fitting 35 tocouple the same to the basin, with a washer at the joint, and a flange58 at the top of the casing to fit in'a recess 60 provided in basins ortubs of the kind. 59 is the head or stopper of the plug fitting in thetop 'of the tube or casing 57.

In the modified form shown in Fig. 2 the chain 27 is omitted, the spacebetween the pistons 21 and 42 being simply filled with oil. The oilbetween the. pistons makesa solid liquid column, as the tight jointsallow no access of air. Accordingly when the knob 10 is pulled up thesuction will carry with it the lower piston 42, and through the bellcrank and other connections the plug valve will be lifted to let out thewaste. When the handle is pushed down the piston 43 is shoved inwardlyand the valve closes.

Ordinarily no chain is needed, but inasv much as wear or leakage mayoccur, so as to dislodge the solid body of 011 between the pistons, thechain may be used, to give a positive connection, and inasmuch as the imaterial are confined.

verylittle friction and the action is practically noiseless. The movableconnections are all inclosed and not ex osed, makin a 5 very neat fit,and one whic cannot be isarranged or disturbed by "children or carelesspersons. Under ordmary conditions the oil will remain in the tubeindefinitely.

Having thus described my invention, what I claim as new and desire tosecure by Let- ,ters Patent is? v 1. The combination with a basin or thelike and a valve therefor, of valve operating devices includinga memberbearing against the valve, a piston, a body of lubricating materialadapted to act on the piston, and a casing in which the piston andlubricating 2. The combination with a basin or the like, and a valvetherefor, of valve operating devices including a casing, pistons in the.casing, a valve operating member engaging the valve and connected toone piston, a handle connected to the other piston, anda body of fluidconfined-in the casing between the pistons. I

3; The combination with a basin or the like and a valve therefor, ofvalve dperating devices including a casing containing a lu bricant, an oeratin member engaging the valve, a ban le, an connections extendinthrough the casing, between the handle an the said member.

4. The combination with a valve, of valve 5' operating devices includinga member engaging the valve, a casing, containing a lilbrlcant, ahandle, and connections between the handle and the said member,including ing operatively connected to the said 'memher, a body oflubricating-fluid in the tube between'the pistons, a flexible connectionin the'tube, between the pistons, and a handle connected to the otherpiston.

7. The combination with a basin or the like and a valve therefor,.ofmeans to operate the same, including a confined body of fluid, a pistonacting on said fluid, and a handle connected to the piston.

8. The combination with a valve casing, a valve therein, and a leverbearing against the valve, of-a tube opening into said casing,

a body of oil confined in said tube, a chain operatively connected tothe lever and movable in the tube, said chain having rollers at its Intestimony whereof, I do aflix my signature in presence of two witnesses.
